Abstract :
In consideration of the defect of original methods, orthogonal geometry ellipse fitting method is compared with algebra method and ellipse definition method. Applying advantage of orthogonal concept and least square (LS) principle, orthogonal geometry fitting method is carried on ellipse. The experiment expressed that orthogonal geometry fitting method make up other method commendably and obtained better result.
